To all whom t may concern: 1

- Be it known that l, ROBERT E. MCGLYNN, acitizen of the, United` States, residing at San Francisco, inthe county of San Francisco and State of California, have invented certain new and useful Improvements in Compression-Pumps, of' which the following is a specification, reference being had to the accompanying drawings.

This invention relates' to certain improve` ments in compression pumps and has for its object to provide a device of this general character wherein the flow of the compression fluid for elevating the liquid is controlled in `substaI-itially an automatic manner.

The invention consists in the details of construction and in the combination and arrangement of the several part-s of my improved compression pump, whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in the appended claims.

In order that my invention may be the better understood, I will now proceed to ,de-

lscribe the same with reference to the accompanying drawings, wherein Figure 1 is an elevational view of a pump [constructed in accordance with an embodiment of my invention and shown in applied position; Fig. 42 is an enlarged view, partly elevationa-nd partly in section, of the controlling means for the pump; Fig. 3 is a view in top plan of the device as shown in Fig. 2, with certain of the parts omitted for the purpose of clea1ness;F1g. l 1s'an enlarged fragmentary view 1u side elevation,

illustrating the means, herein embodied, for' operatively supporting the delivering pipe; and Fig. 5 is an .enlarged fragmentary view, partly in elevation and' partly in section, of the drum and the lower extremity of the discharge pipe, as herein set forth.

As .disclosed` in the accompanymg drawings, 1 denotes a drum of predetermined dmensions adapted to be suitably positioned within a cistern or the like and "has produced in its lower end the induction ,opening 2 under control of the upwardly moving check valve 3 which may be of any ordinary or preferred construction and extending through the upper end or head of the drum and terminating adjacent the lower end or head: thereof is the discharge pipe 4 having its inner or lower end open and under con` trol of the inwardly movable' swinging check 5. l

At a predetermined locality relative to the cistern is positioned a supporting member 6, herein disclosed as an uprightframe, in the upper-extremity of which is rotatably supported a lshaft 7, to which is suitably aflixed a drip pan 8, said drip pan being provided with an intermediate partition 9 dividing the same into two compartments C and- C. Discharging into the drip pan 8 is a drip pipe 10 leading from a suitable source of supply and serving for a purpose which will hereinafter be more fully set forth. p

Disposed transversely of the frame 6.in close proximity to and below the shaft 7 is a cross arm 11, to the opposite extremities of which are pivotally connected, as at 12, the inwardly directed and reversel-y disposed arms 14 and 15, the free extremities whereof being provided with the oppositely arranged cam slots 16, through which projects the' pin 17 projecting laterally from the rock arm 18 fixed to the adjacent projected extremity of the shaft 7 whereby it will be perceived that upon tilting of the drip pan 8, the arms la and 15 will be nica-tion with the interior thereof through.

the upper end or head, as is believed to be clearly shown in the accompanying drawings. The casing 20 is in suitable communication, as indicated at 28, with a suitable source oit compressed fluid, such as air, while the casing 2l is in communication directiy with the atmosphere, and each is under control of the valve member 24l'coacting with a suitable valve seat 25. The valve member within the casing 20 is operatively eugaged with the arm 14 while the valve me1nber 24 of the casing 21 is operativelyengaged with the arm 15, whereby it will be perceived that when the How through the member 20 is inclosed the exhaust valve casin will be open and vice versa.

Vhile other means may be employed for imparting rocking movement to the drip pan Sor its equivalent', I prefer to employ the arrangement as disclosed in the accompanying drawings, wherein it will be perceived that upon the requisite quantity of fluid being delivered into the compartment C, the casing -2O will be closed and the casing 21 opened, as the depression of this end of the pan will rock the arm 18 the requisite distance to occasion this result. lt will also be observed that Vwhen the drip pan is in this adjustment, the partition 9 will be so disposed relative to the drip pipe 10 as to cause the tluid to enter within the compartment C', whereby the condition of the casings 20 and 21 wiltfbe reversed whereupon the compressed tluid will be permitted to enter within the drum 1 and force the fluid therein upwardly through the discharge pipe 4, and the delivery of the fluid within the several compartments C and C of the drip pan 8 is so regulated as to assure the operation of the valve members 21 at the time the liquid to be elevated has been substantially entirely forced from the drum 1 into the pipe 4, or the drum 1 has been filled by the entry of the liquid therein through the induction opening 2.'

In order that the liquid discharged within the compartments C and C may be exhausted, I lind it of advantage to produce in the bottoms of said compartments adjacent their outer ends, the transverse row of r'estricted openings 25.

From the foregoing description, it is lthought, to be obvious that a compression pump constructed in accordance with my invention is of an extremely simple and comparatively particularly well'adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason Ido not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:

1. A device vof the character described comprising a conduit leading from a suitable source of compression, a valve interposed in said conduit for controlling the inexpensive nature and is4 llow therethrough, an exhaust valve in communication with said conduit, reversely directed swinging. arms, an operative connection between one of the arms and the first mentioned valve, an operative connection between the secondA arm and the exhaust valve, the adjacent extremities of the arms being provided with reversely directed cam grooves, a rock arm, a pinv carried by the rock arm directed through both of the grooves, and means for imparting rocking movement to the arm.

2. A deviceV of the character described comprising a conduit leading. from a suitable source of compression, a. valve interposed in said conduit for controlling the flow therethrough, an exhaust valve in communication with said conduit, reversely di-` rected swinging arms, an operative connection between one of the arms and the first mentioned valve, an operative connection between the second arm and the exhaust valve,

the adjacent extremities of the arms being provided with reversely directed cam grooves, a rock arm, a pin carried by the rock arm directed through both of the grooves, and gravity means for imparting rocking movement to the arm.

3. A device of the character described comprising a conduit leading from a suitable source of compression, a valve interposed in said conduit for controlling the flow therethrough, an exhaust valve in communication with said conduit, reversely directed swinging arms, an operative connection between one of the arms and the first mentioned valve, an operative connection between the second arm and the exhaust valve, the adjacent extremities of the arms being provided with reversely directed cam grooves, a rock arm, a pin carried by the rock arm directed through both of the grooves, a drip pan supported for rocking movement, said arm being connected thereto, a partition dividing the pan into two compartments, means for delivering a Huid within the compartments of the pan, said compartments being provided with discharge openings.

In testimony whereof 1 hereunto affix my signature in the presence of two witnesses. ROBERT E. MCGLYNN.
